Module-assembly type domestic waste sorting device

Abstract

The invention discloses a module-assembly type domestic waste sorting device which comprises a box body and also comprises a domestic waste feeding section, a broken bag winnowing section, a magnetic separating section, a water content sorting section and an organic matter section which are arranged in the box body. The box body is externally provided with different domestic waste collecting boxes which correspond to all the sections; the domestic waste feeding section is provided with a domestic waste inlet and an automatic conveying belt which is arrange at the bottom of the domestic waste inlet; the broken bag winnowing section is provided with a knife-type multipurpose roller screen, a domestic waste hopper, an automatic conveying belt and a winnowing machine which is arranged on the side part of the broken bag winnowing section; the magnetic separating section is provided with a magnetic separator and an automatic conveying belt; the tail end of the automatic conveying belt in the broken bag winnowing section extends to the top of the magnetic separator; the water content sorting section comprises a slide plate and water tanks which are connected in sequence by pipes and are used for separating solid from liquid; the organic matter section comprises a water tank and an automatic conveying belt, wherein the water tank is connected with the water tank in the water content sorting section by pipes, and the automatic conveying belt is used for conveying the domestic waste to the domestic waste collecting boxes. The module-assembly type domestic waste sorting device has novel structure, adopts the totally-sealed Module-assembly type and is convenient to install and transport.

Description

technical field [0001] The invention relates to the field of garbage treatment systems, in particular to a fully-automatic fully enclosed module-assembled module-assembled household garbage sorting device. Background technique [0002] The current status of domestic waste treatment in my country: With the development of social economy, the output of domestic waste is also increasing year by year. According to statistics, Chinese cities already account for 140 million tons of the 490 million tons of garbage generated in the world every year. Over the years, the amount of garbage accumulated in Chinese cities has reached as high as 6.6 billion tons, occupying more than 500 million square meters of land, and the annual growth rate is approximately 8%. Two-thirds of cities in China are surrounded by garbage. What is even more worrying is that 1 / 4 of the cities in China have developed to the point where there is no suitable place to pile up so much garbage. Urban people have n...

AI Technical Summary

Problems solved by technology

The process of garbage incineration seriously pollutes the atmosphere, and the operating costs of dealing with such toxic gases are very expensive, which is not in line with my country's national conditions at all.

[0006] The accumulation of compost is seriously polluted, seriously polluting the surrounding environment, and bringing great hidden dangers to local sanitation and epidemic prevention

The degradation of organic matter is not complete, the treatment is not sufficient, and the residue will still cause garbage pollution

Long-term use of compost products will cause soil surface deposition, damage the soil, and endanger crops

[0007] To sum up, my country's current domestic waste treatment technology is basically at a low level, and it is difficult to achieve harmless and resourceful waste treatment, let alone industrialization. In the construction of a new socialist countryside and a conservation-oriented society in our country And in the future social and economic development, it will become a restrictive factor

[0008] The existing common comprehensive garbage treatment equipment is usually bulky and inconvenient to transport, and most of them need to build factories, add deodorizing equipment, and then carry out comprehensive treatment

For example, the large-scale domestic waste treatment equipment invested by Meishang International in Caolu Town, Pudong, Shanghai, and the comprehensive treatment equipment for landfill and incineration of domestic waste in Shanghai Jiangqiao, both invested more than 100 million yuan, but neither can solve the problem of secondary pollution

[0009] And according to the comprehensive garbage disposal equipment, the supporting factory building is at least 1000-2000m 2 , the cost is 8 million to 16 million yuan; it must be equipped with a deodorization device of 8 million yuan, and the resource reuse rate is only about 45%; the cost of landfill and incineration is 65-240 yuan per ton, which is expensive and cannot be solved Secondary pollution, unable to solve heavy metal pollution and unable to extract high-quality fertilizers, often treat all garbage together, and the resource utilization rate is not high
